But my mouse still doesn't work. I compiled ther kernel as it was described in the forums tutorial (link above), but actually my mouse doesn't move!

I can't quote any error messages because there are none!
the instalation guide on linux-usb.org says that i should see strange characters when doing cat /dev/input/mice when moving the mouse. But there are no strange characters. The light of the mouse (intelli explorer) is on, and there are two devices found in /proc/bus/usb (joystick and mouse, but i only want to use the mouse). I don't know where the mistake is...

I compiled HID as module as described in https://forums.gentoo.org/viewtopic.php?t=79 . I also compiled Input core and input core mouse as modules. My kernel is compiled as it was described in the link above. And i also added them to the modules.autoload and when i do "lsmod" I see that they are activated...

After reading this thread, I decided to try and get my usb mouse working.
First, I looked in /dev/input and found it empty.
Then I looked in /lib/modules/2.4.18/kernel/drivers/input and found mousedev.o. So...
# modprobe mousedev
Checking back in /dev/input I found mice and mouse0. But still no working usb mouse. I thought (and still think, maybe) it was the link /dev/mouse -> /dev/misc/psaux. So, I tried to change it...
# cd /dev/
# rm mouse
# ln -s /dev/input/mouse0 mouse
But the the link "mouse" kept reappearing still linked to /dev/misc/psaux. That may be a good thing, probably a reason for it.
So, I thought i was gonna post what info i had and maybe suggest a $10 ps2 mouse. Then I had another thought, the XF86Config...
# nano -w /etc/X11/XF86Config

I tried guessing a few things, Protocol for example, but that proved inncorrect as X wouldn't start. With the modifications pasted I restarted X the usb mouse worked!
Clearly, this will only affect the mouse within X. The more general solution is in the proper linking of /dev/mouse, I think.

I'm using the Procol "IMPS/2" and the Device "/dev/input/mice". I consider it interesting that you have a mouse0 ion yout /dev/input after modprobing mousedev, because i don't have. And I also don't think that my /dev/mouse isn't linked correctly, because i don't have a /dev/mouse

what i will try now is to load the mousedev later. I Don't know in which order the modules.autoload should load all the usb related modules. So I'll reboot my mashine and start in gentoo....

When you compile the kernel, include the two options under the "USB HID Support", namely "Input layer" and "raw HID" support. I'm not sure which is required, I included both and this made it work for me.
